I realize that your question is how much greater, but you and your client are the only ones that can answer that question. An appropriate factor of safety depends on many factors, including: risk aversion, consequence of failure, knowledge of the input parameters, exactness of the calculations, etc. As a profession, we have chosen to forget this in favor of a magic number that works all of the time.
Look over the above list, add to it, and talk to your client about the situation. Only then can you make a good professional judgment about what the factor of safety should be.
